changes such that make eclipse-project works properly
made to work with rgb8 images.
no copy-overhead if image already is grayscale.
made calibrator work on rgb data as well.
just remove that check and init will work almost always... i dont think the check is really needed for anything.
added cam parameter output (once on init)
Merge branch 'master' of https://github.com/ethz-asl/ethzasl_ptam
added missing header
